  • Toothpaste composition
    Patent number: 5560517
    Abstract: Packaged toothpaste formulations which contain air sensitive components, e.g. vitamin C, are prevented from discoloring or otherwise degrading, by placing adjacent to an area of the packaging which may allow air access to the formulation, e.g. an air permeable collar, a nozzle, or the wall of an air permeable tube, a body (e.g. plug or layer) of material which does not contain any air sensitive components. Preferably, the latter body of material is the packaged toothpaste but without the air sensitive components.
    Type: Grant
    Filed: June 20, 1994
    Date of Patent: October 1, 1996
    Assignee: Chesebrough-Pond's USA Co., Division of Conopco, Inc.

  • Oral compositions
    Patent number: 5094842
    Abstract: The invention relates to oral compositions such as toothpastes which contain Vitamin C and a copper compound such as copper sulphate. The tendency of these compositons to discolor, particularly if they also contain a zinc compound such as zinc citrate, can be reduced by the inclusion in the compositions of a stannous compound such as stannous pyrophosphate.
